Where to source 6MGE in the U.S. ?

I located one source that shows in stock, got voicemail and was never called back.

These were common in the '90s and available from nearly all the engine importers then. Their numbers dwindled real quick; probably because the 6mge was never an option in any Toyota automobile exported to the United States. I've seen several listed over the years that the importer didn't really have in stock but they showed it in stock on the website just to get your interest and then when you call they would try to sell you a 7mge or a jz. Every once in awhile, up until about five, six years ago, you used to see one on ebay from an engine importer. I found one listed on ebay from jdmenginezone in July, 2013, which I bought and put in my '84. Prior to that I bought one from an importer in May, 2012 and I bought three 6mge engines from an importer in Houston, TX back in 2002. They gave me an excellent package deal.
I don't know where people keep getting that 200hp figure from but since the 7mge was also listed at 200hp, I always figured people were confusing the two; just like there are a bunch of people out there that swear the 6mge was in the '86 Supra because they see the 2.8litre and 3litre listed as options whenever they want to buy parts for an '86. 170hp. Especially with the flapperdoor-style AFM used in the Celica Supra.

Excellent feedback 4SFED, much obliged. I am trying to decide what to do with my 87' Cressida since the usual oil leaks have arisen on my 5MGE. Since the engine will be out, I am pondering an engine swap. I'd really like a 1UZ but I just don't have the time and resources for such an involved swap.

So I was looking around for something that could be done in a weekend. I am 39, prefer my high speed kicks on a moto. So I figured 200hp coupled to a 5 speed would make for some fun spirited commuting with the suspension dialed in and lightweight forged wheels. I have a line on a carbon fiber manufacturer, and with the ease of simply bolting on, thought it might be worth putting the car on a diet and get some cool factor points.

Of course like most of us, I am on a budget. But if I could devise a plan where I can add as I go over the year, I could work my way to the desired results.

I am aware of all the various options, I suppose I need to research more and see which is less involved when it comes to harness fabrication, required adapters etc.

The 6mge was the easiest way to add a few horses with a simple swap back when they were plentiful. Like I said above, I have swapped in five 6m engines in the past. I still have one and a friend in Northern WI has an '85 that I swapped for him. The others I've sold over the years - one went to Michigan, another to Missouri, and another to Canada.
Some people say "Make your own 6m" - just go get a 7m and cannibalize what you need from your 5m and 7m to make a 6m, but my motivation was to do a quick easy swap for a little more getupandgo. When the ready-made 6m engines got scarce, I started putting 7mgte engines in my Supras.

I'd just stick a 7MGE in it. Its a relatively easy swap. The problem with the 6M is it was last used in a car like 30yrs ago how many cars that old in Japan now getting junked? Even regular old 2JZGTEs are starting to dwindle.

You probably have better luck finding one in a junkyard here. They were used pretty interchangeably with 5Ms back in the day.

Way too much for a 7MGE. Plus you have to source a bunch of parts from a US car anyways to make the swap. 7MGEs are like the bottom of the barrel engines in Mk3s pretty much everyone rips one out to go JZ. You should be able to find someone that is doing that and you get all the parts you need. The find another Mk3 parts car to cut the 2 plugs you need off the body to do the swap.

Frankly the 2JZGE is a much better choice, but its a little more costlier of a swap. With the 7M you can reuse the motor mounts, exhaust, bellhousing and flywheel.

Thanks for all the feedback. I think I will just keep it stock for now, start collecting the parts for a 1UZ swap.
Find another budget car to drive in the interim, take my time and build it right the first time. I want it factory clean and am willing to put in the time and effort.

Again, many thanks for all the ideas, knowledge.

Even a stock 1uz will be tons of fun in a mk2, but it is by no means an easy or cheap swap. The header woes are probably the worst part, mating it to a manual transmission is the most expensive part.

You can actually get 200hp out of a 6mge (built or bought) but it takes a little work and definitely standalone fuel injection, which really isn't that big of a deal these days. Like Deanfun said, there were 2 flavours of 6ms in Japan the one that makes 170ish hp with the same efi our 5ms came with, and then the one that one year of crown at the end had and it came with the same Karman Vortex AFM that our 7mgtes got and that probably made close to 190crank hp. I'm making 184 to the wheels right now, which is over 200 crank, and even more torque. Its quite fun, and I'm not done yet either. See my build thread if you do decide to go that route...

200bhp out of a 6MGE is easy, 200whp out of a 6MGE is expensive and a PITA

but even stock the 6MGE torque is beefy.


168/188 to the wheels here, with a 4.10 set and still feels torquey for daaaays. The majory drawback for the 6M in power is bottlenecks and engine management. Go standalone from the start and update the electronics and you're already ahead without having to do anything else.

There will always be aftermarket forged slugs available, and they will always be 700+usd. A 6m just needs good plus sized oem replacements, and unfortunately those are drying up. But I think you can still get .5mm over ones, just not the 1.5mm over you used to be able to get (nice displacement bump). A nice sorted 6m is alot of fun, but a stock 2jzge will pretty much give you the exact same powerband without any dicking around. 7mge's are easier to install but are getting hard to find with low miles. Even 2jzges are starting to become difficult to source from engine importers. Not too bad to get domestically, but hard to find low enough mileage then.

DIYPNP MegaSquirt by https://www.diyautotune.com is definitely the easiest and cheapest way to go standalone in our cars, they have an almost plug and play kit for our car. Lots of other options though.

6mge is the bomb! Especially if you slap a turbo on the side of it and do some fuel upgrades, beefy torque like Tanya said. Just go to all the pull-a-parts and look under some hoods. If you really want a 6mge and dont wanna wait then go to the junk yard and buy a 7m and plan on using the head and the pistons from your 5m, but dont expect all your stock pulleys and belts to work unless you can get a crank balancer from a 6m somewhere...

I didn't want to start a new thread. Besides a U.S. OEM harness, what else would be needed for JDM 7MGE? Sump?
I have a line on one for a decent price, using the car for touring not racing. Simply a backup car I take trips in.

I thought since the engine would be out, get a little more power in the process. Toymod site makes it seem simple to swap JDM 7MGE

Into a Mark 2 Supra?
Edit:
Never mind - just read back to beginning. Is it a front sump 7m? That's what you need - I get them from newer Cressidas.
Do you have a link to Toymods where you're looking at swap info?

I don't really see the appeal in a 7MGE swap unless someone gave you the motor for free. A 2JZGEs can be picked up for dirt cheap from bazillions of Lexus model from the 90s and early 2000s and is a way better motor. Many get ripped out for 2JZGTE swaps in those cars. If you're patient you can pickup a take out for $400-600.

Unless you're really lazy there isn't much advantage in the Cressida 7M since you can swap oil pans and pumps with the 5M. The intake manifold is a little different but that is about it.
 
#28 ·
Not lazy, just looking for the easiest and less time consuming route to get a new engine into replace my tiring 5M.

This will be an everyday driver, touring car. Not looking for massive performance.
I am going back to moto's for my performance kicks, just need a good GT, A to B car for rainy/hot days.
7M is easier install wise from what I can deduce.

The 7M in questions has all I need, without having to source each piece or take on a whole vehicle to part out, which I do not have room for nor the time.
 
#29 ·
I get what your saying and though I have a little love for the 7m I'd still go for a 2jzge if sourcing one. Besides that it will make 20% more power and get probably 10% gas milage, they made the things up till 2005 whilst its already getting hard to find many 5m parts and 7m stuff is just about to hit that point too.

The only thing that makes a 2j swap any harder is the engine mounts. Which various peeps have made and sold over the years...

https://xcessivemanufacturing.com/t...sis-and-suspension/toyota-mx83-jz-mmb-ze.html

I "think" these would work. Those years of cressida were front sump and mac struts, I would assume they used the same engine mounts as 5ms in mk2s. I would research that one for sure before buying though.
 
#31 ·
Some serious food for thought. Picking up a 83' XL600R hopefully this weekend, once that's sorted and reliable for daily use, I will look at the 2J swap.
Y'all make a good argument for that swap. And with a way to get around, I will be less stressed about the time of performing the swap.

Buy a 2jzge jdm swap. They are not very expensive and have everything needed for you to swap it aside from the motor mounts, driveshaft, etc... IIRC I have seen them less than $1k. It will be more reliable, more powerful, and all around a better swap. If you get lucky and get one from a soarer, it is a slip yoke like the sc300, instead of the 3 bolt flange like the aristo/gs300, and uses the same splines as a mk3 auto, so all you need for the driveshaft is the front half of a mk3 auto driveshaft, change to the mk2 center bearing, mk2 rear 5 speed drive shaft, and your set. The only downside is the oil pan is not a front sump, but there are literally dozens of guys willing to swap their front sump oil pan and baffles for a mid sump setup, sometimes they will even give you cash on top as the mid sump pan is worth much more. GS300/aristo is front sump. Id grab the soarer/sc300 one though due to the ease of the drive shaft with that swap. Oil pan change is far cheaper than a custom drive shaft.

Did he say he was going auto or was auto? I missed that if he did. Pretty sure even the later w58s still use the same spline as the mk2. Stock driveshaft should work with almost any year w58. However, that is the one downside of the 2j swap. Although finding wrecker or imported 2jzges isn't too bad, its very rare to find the jz w58 bell housings or 2jges with w58s attached. They're about 300 bucks new, readily available, but they can be tricky to find used when you actually need one and they often end up costing about the same used.

IDK if he is or not, I was just thinking cheapest route to do the swap, which would be auto. The w58/r154 BH's, when found are $300+ typically, then you need the flywheel, clutch, etc... I know of this as I have contemplated doing it to my 85 which is auto. With its 4.10 diff, which is close to the 4.08 of my gs300, and the 6-700lb weight reduction that the chassis provides, it should be a hell of a fun car with just a header, exhaust, and intake pipe and filter. Same mods I have on the gs. Even as heavy as it is, it will still get up and go once its moving. Dead stop take off kind of sucks, but its a lot of mass to get moving, and non lsd, so I get the 1 wheel peel from time to time if I hit the gas too hard, even on new tires. If i ever luck into a sc300 for dirt that runs great but is wrecked, I may still do this.
